My invention nela-testo an improvement in handles and a method of makingthe same, especially a handle for a valve stem= or other part-adapted tobe turned or ma-; In general my object" ni-pulated by hand. is to;produce a ring-shaped handle in a facile and inexpensive way by thesteps heme-matter described: and more particularly pointed-out inthecla-ims.

In the annexed drawings, Fig.1[is aside elevatien oiia valve stemhavin-glanenlarged head with a cross bore therein, and Fig. 2 is a sideview of a; round rod adapted to be inserted within said bore; Fig. 3 isa sectional View of the valve stem showing the rod as it appears whenfirst introduced in the bore. Fig. 4 is a cross section of the headshowing the protruding portion of the rod flattened, and Fig. 5 'is avertical section through the stem and. the rod as these parts appearunited together when the protruding portions of the rod have beenflattened and expanded vertically. Fig. 6 is a side elevation of thecompleted stem-and handle, and :Fig. 7 is an, edge elevation thereof.

The invention comprises a main body part, which in the present instanceconsists of a round needle valve 2 having a round stem 3 formed with around enlargement or head 4; at its upper or outer end in which a roundopening 5 is drilled from side to side at right angles to the axisof-the head and stem.

This part may be made quickly and cheaply in an automatic screw machine,but lacks means to permit it to be gripped and turned by hand. Suchmeans may be provided by inserting a round rod 6 of predetermineddiameter and length within the opening or cross bore 5, for example, asdelineated in Fig. 3. A body part and handle member so constructed maynot be particularly novel,

but by taking the following simple steps a very rigid union of the partsis effected, and a flat wing-shaped handle isproduced which permits arotatable movement to be imparted by hand with a firm grip and withoutdistress to the fingers.

Thus, a rod 6 is cut to a given length and the ends are cut straight atright angles to the axis of the rod. This piece is then inserted toabout its middle in'c-ross bore 5 so that the. end portions protrudeapproximately equal distances on opposite sides of head 4. Theprotruding end portions, which are round, are then subjected to pressurep ni i head i is'a eni -ng arena-l tion may. be produced by diesconstpucted. tov apply: equal pressure simultaneously eaten. equal areason opposite sidesof head a, and closely contiguous :to thecincuanf-erence-oii the head. This operation notionlyfiattens the moundrod Ian-tit also displaces the stock: directly involvedpcagusing it to.flow apex-- p and in opposite directions longitudinally ogfi the headthereby widening the protruding ends of the rod as well as flatteningthe same. The pressure being localized contiguous to and parallel withthe straight sides" of the head the stock which is flattened crowds intothe sharp round corner edges 7--7 at the opposite ends ofround crossbore 5, only a segmental part of the circular edge at the topand-'bottom'of the cross bore being involved. The stock undercompression also tends to crowd toward the center of head 4 whenbothends of therod' are compressed.simultaneously, thereby swelling theround central portion 8 of'the rod within the round opening in the head.In this way round part 8 of the rod becomes wedged within the head andthe fiat wings 9 are crowded into interlocking engagement with the sharpcorner edges 7 so that the rod cannot turn on its own axis or work freelongitudinally of its axis. In fact the completed handle isso tightlyfixed Within the head and the joints so neatly finished that it appearsoncasual inspection to be an through, and a round rod extending throughboth ends of said opening and having the projecting portion fiattenedandwidenedto 3. A'handle, comprising a mam body part having a round openingtransversely therei provide a pair of combined gripping wings andlocking elements for said rod.

5. A' method of producing a handle comends of a cross piece at each sideofa main member through which said cross piece extends and forming apair of flattened wings While simultaneously interlocking said partstogether at their lines of juncture.
